What Is IVF and How Does It Work? A Comprehensive Guide to In Vitro Fertilization

For many individuals and couples dreaming of parenthood, the journey can sometimes lead to advanced reproductive technology options. Among these, In Vitro Fertilization, or IVF, stands out as one of the most effective and widely used fertility treatment methods. If you've been exploring options for conception, you might be asking, "What is IVF and how does it work?"

At Wombs Fertility, we understand that understanding the complexities of IVF treatment can be overwhelming. Our compassionate and experienced team of fertility specialists is dedicated to demystifying the process, providing clear information, and guiding you through every step of your in vitro fertilization journey with care and expertise.

What Exactly Is IVF (In Vitro Fertilization)?

IVF stands for In Vitro Fertilization. "In vitro" is Latin for "in glass," meaning fertilization happens outside the body, in a laboratory dish. This process involves retrieving eggs from the woman's ovaries and fertilizing them with sperm in a lab. The resulting embryos are then cultured for a few days before being transferred back into the woman's uterus, hoping for successful implantation and pregnancy.

IVF is often recommended for various types of female infertility and male infertility factors, including:

• Blocked or damaged fallopian tubes

• Severe male factor infertility (low sperm count, poor motility)

• Endometriosis

• Ovulation disorders

• Unexplained infertility

• Genetic conditions (with preimplantation genetic testing)

• Failed attempts with other fertility treatments like IUI

How Does IVF Treatment Work? A Step-by-Step Breakdown

The IVF treatment process is a meticulously planned and monitored journey, typically involving several key stages:

1. Ovarian Stimulation (Controlled Ovarian Hyperstimulation)

• Purpose: To encourage the ovaries to produce multiple eggs, rather than the single egg typically released in a natural cycle. This increases the chances of successful fertilization and embryo development.

• Process: You will receive daily injections of fertility medications (gonadotropins) for about 8-14 days. Your fertility specialist will closely monitor your progress through regular blood tests (to check hormone levels) and ultrasound scans (to measure follicle growth).

2. Egg Retrieval (Oocyte Retrieval)

• Purpose: To collect the mature eggs from the ovaries.

• Process: Once the follicles are mature, you'll receive a "trigger shot" to induce final egg maturation. Approximately 34-36 hours later, the egg retrieval is performed under light sedation. A fertility specialist uses an ultrasound-guided needle inserted through the vagina to gently aspirate fluid from each follicle, collecting the eggs. This is typically a 20-30 minute procedure.

3. Sperm Collection and Fertilization

• Purpose: To fertilize the retrieved eggs with sperm.

• Process: On the same day as egg retrieval, a sperm sample is collected from the male partner (or donor sperm is prepared).

• Fertilization Methods:

  • Conventional Insemination: Sperm and eggs are mixed together in a culture dish, allowing fertilization to occur naturally.

  • Intracytoplasmic Sperm Injection (ICSI): A single, healthy sperm is directly injected into each mature egg. This method is often used for male factor infertility or if there have been previous fertilization failures.

• Embryo Culture: The fertilized eggs (now called embryos) are monitored and grown in the lab for 3-5 days.

4. Embryo Transfer

• Purpose: To place the selected embryo(s) into the woman's uterus.

• Process: This is a typically painless procedure, similar to a pap smear, and usually requires no anesthesia. The fertility specialist inserts a thin, flexible catheter containing the embryo(s) through the cervix and into the uterus, guided by ultrasound.

• Number of Embryos: The number of embryos transferred is carefully decided with your fertility specialist based on your age, embryo quality, and other factors, to optimize success rates while minimizing the risk of multiple pregnancies.

5. Luteal Phase Support and Pregnancy Test

• Purpose: To support the uterine lining for implantation and confirm pregnancy.

• Process: After embryo transfer, you will continue progesterone supplementation (usually vaginal suppositories or injections) to help prepare and maintain the uterine lining. Approximately 9-14 days after transfer, a blood test will be performed to detect pregnancy.
